Service Advisory for SR series.

Just want to give you guys a heads up that there are eight screws holding the rail system. If the rail become loose please tighten all eight screws with a 1.5mm Allen key evenly across. Add a little loctight if you like.

Thanks for the tip, but um I have another thing that has happened. If you look at the RAS compensator thing (takes over the delta ring on standard m16 guns) there are holes if you look having the dust cover near your face and the flash hidder is to the front, there are holes in the compensator that are drilled perfectly, but there is also two pins, one on the left and one on the right that are inside the holes (NOT THE SCREWS IN THE PICTURES) are those just for looks or do they hold the RAS in place cause mine are giggling a little bit moving back and forth.

After tightening all of the screws as tight as I can get them, I hear a noise when I lean the gun diagonally down and diagonally up. It sounds like 2 metal pieces that are not tight and are sliding forward and backward and hitting one another. The sound seems to be coming from the D Ring type thing at the end of the RIS/RAS. Anyone have any ideas?

Your having that sound too? Its the problem I was just talking about in my post before yours. Its the two pins inside the RAS compensator (the thing that replaced the delta ring) where the holes are drilled into the back. There are two pins left and right. Mine are loose and so are yours. I am trying to figure out if they two pins on the left and right side inside the holes are just there for looks or if they actually hold the RAS in place.

Guys... those are two guide pins that position the RAS itself. It's common RAS design and if you haven't install aftermarket parts, picture below is a RAS kit from King Arms.

See the two pins on the bottom? That's what you are looking at on the RAS after it's installed and they are normally loose.

BTW, King Arms's RAS don't even have those 8 screws and if you look closely. They just look like some fugly welded mark. I rather have the KWA RAS.

Yeah I figured that out last night when I was looking at KAC RAS. Good job Kwa for making the most Accurate KAC RAS I've ever seen way better than the G&G SR25 KAC rail and best of all, the VLTOR gas block is just smexy.

Yeah but even though those pin things are loose like that, does that mean that my whole rail system should be able to turn to the right (if you were looking down your sights right) a full half a centimeter? (I know it doesn't seem like a lot, but for what I expected from a KWA its a big deal lol)

I don't believe that the pins support anything. It is the screws I believe that are loose allowing the ris to rotate like you descibed. Just realign them and then tighten the screws that allizard has in the pictures and remember there are 8 screws total.

How do are you supposed to align the screws? Is there some distinctive sound it makes or can you feel it?

Well, my problem is that my RAS rotates about 1cm to the right, and after tightening the screws, nothing happens, if I keep tightening the screws, the screws will strip. I watched the video on how to fix the delta ring wobble, but dont feel comfortable do this myself, what should I do? Would AirsoftAtlanta be able to help me, considering I bought the gun from them and they are near where I live?

If you really can move 1 cm then the gas tube is not in the receiver at all. What's prevent tightening up the ras is the gas tube is in the way. You need to move the tube out of the way to tight it and at the same time it lines up to the next hole. There is a $30+ fix call the RAS FIX, basically it cramps on the RAS and the upper receiver.

Well, I might be exaggerating a bit, it is probably more like half a cm.

Hey here is what I do. If you have a mount or even rail cover or something that will run over the two rails of the RAS and the main body top RIS rail, then take a dry towl and hold on to the delta ring thingy really tight and tighten by turning in the direction of the dust cover and mag release side and make sure you put as much pressure as you can and it will stay on solid very nicely. Mine started to wobble a bit today and I just used my shirt and a optics mount to center the rails and twisted and when I was done, only like a minute later, solid like a rock again.

Lol this is why i ordered a ras fix with my sr-12. Im sure it will be really solid and i know how to fix the wobble if there is any, but still, why not have that extra reinforcement? Im super picky when it comes to rail sturdyness/movement so i had to have one LOL! Thats just me though
